The first column in the route entry field defines the type of data, as follows:
S String (alphanumeric)
P Pick List (alphanumeric)
N Number (numeric)
T Tag (alphanumeric)
H Hidden Database Key (alphanumeric)
L Leak Rate (numeric)
D Dead Band Rate (numeric)
R Response Factor (numeric)
C Comment (alphanumeric)
The String, Pick List, and Number field types may have more than one
entry in the route fields. All other types may be used only once in the route
fields.
An optional "X" character may be added after the data type to indicate that
that entry field may not be edited, it is only shown on the TAG screen.
The second column of the route entry field defines the field width, which is
used to define data storage size, display data on the probe, and during file
transfers. The sum of all defined fields may not exceed 365 characters. Each
field may not be larger than 60 characters, with the exception of the Tag
field and Pick lists (16 characters).
The third column of the route entry field is the label for the route entry
field, which is displayed as the column header in the route database file and
on the probes as a field prompt. Each label may be no more than 12
characters. Each route entry field is ended with <CR><LF>.
Note that the leak source, repair method, and comment fields are not
actually stored as part of the route entry. Instead these items are stored with
each logged data point. They are included in this section so the user may
define the pick lists and comment field size.
The next section of the file defines the PICKLISTS. There may be up to 8
pick lists included in the database definition (this includes the LeakSource
and RepairMethod lists), but none are required. Each pick list may have up
to 16 items consisting of no more than 16 characters each. The pick list
definition consists of multiple lines of data. The first line is the pick list
label as follows:
LABEL=llllllllllllllll
Where llllllllllllllll is the pick list label which is left justified and terminated
by <CR><LF> at any time (does not require 16 characters). The label must
match the label previously defined in the ROUTE FIELDS section of the
file. Each additional line is a pick list entry. The pick list is terminated by
